New Era of Defense Optics: Design Breakthroughs of LGRIN LENSES

Imagine ultra-thin, lightweight lenses that provide unparalleled optical performance - a wider field of view, crisper color clarity, and better target identification than traditional glass optics. This breakthrough is made possible by Peak's HawkAI technology, which harnesses the power of layered gradient refractive index (LGRIN) lenses.

The Origins of LGRIN

Long before LGRIN, there were the fundamental concepts and mathematics for GRIN (Gradient Refractive Index), LGRIN’s precursor, which was invented by James Maxwell (1831–1879). He formulated a set of equations known as Maxwell’s equations. In the 1950s Harold Hopkins and Narinder Kapany pioneered the use of multiple glass lenses to correct optical aberrations in high-quality imaging systems. This work and more is what paved the way to allow for better and more specialized optics.

The serendipitous start to the development of LGRIN began over 20 years ago through the collaboration of researchers from DARPA, Naval Research Lab (NRL), Case Western Reserve University (CWRU), and the Department of Energy (DOE). 

In 2002, researchers at CWRU presented the first draft of NanoPlex, a revolutionary translucent metamaterial. At the same conference, CWRU's team met with NRL's optics experts who were working on GRIN and other optics programs. This meeting sparked the idea of combining NanoPlex's unique layering capabilities with gradient refractive index (GRIN) optics models, and this convergence gave birth to the LGRIN concepts that power Peak’s HawkAI-designed lenses today.

The NanoPlex Advantage

What makes NanoPlex so special? Unlike naturally clear materials in a single layer that become opaque when layered, NanoPlex can maintain translucence across thousands of layers. This remarkable property is the key enabler for Peak's LGRIN lens design and manufacturing.

With over 800 engineered versions of NanoPlex, Peak has an unmatched ability to create lens "recipes" tailored for specific applications and needs. Our cutting-edge AI software, HawkAI, uses a Peak-invented new class of mathematics based on Maxwell's equations and accelerates the lens design process from years to months. Beyond our software and recipes, Peak’s advanced manufacturing, shaping lens curve layers, and diamond-turning the lens to prescription processes are unmatched and represent another competitive advantage almost impossible to replicate.

Unrivaled Performance and Protection

And there are even more ways HawkAI-designed LGRIN lenses offer game-changing advantages over conventional optics:

1. Unparalleled Optics Performance: LGRIN technology improves the field of view, provides superior color clarity, and enhances distance vision for applications like night vision goggles, fire control systems, and unmanned aircraft system (UAS) reconnaissance.

2. AI Optics Design: Peak invented a new class of mathematics based on Maxwell’s equations and created our patented AI-based design software. 

3. Engineered Translucence: The unique translucent NanoPlex metamaterial allows Peak to build LGRIN lenses that no other company can replicate.

4. Lenses Shaping and Diamond Turning: Peak's advanced manufacturing processes can precisely shape lens curves by removing layers as thin as two molecules. 

5. 100% US-based IP and Design: Over 20 Global patents protect Peak's LGRIN lenses, NanoPlex, and manufacturing processes. All research, engineering, and manufacturing are conducted in the United States, and materials are sourced from the U.S. and allies-only supply chain.

With HawkAI-designed lenses being up to 2x thinner and 50% lighter than glass optics, the possibilities are endless - from enhancing military systems to revolutionizing surgical equipment and consumer cameras.

The journey of HawkAI is just beginning, and Peak is poised to continue experimenting with our innovative NanoPlex for decades to come, solving macro-scale global problems with our groundbreaking nanoscale technology.
